Why do fuel tanks of a rocket need to be kept cold before launch?
Many rockets (Including the Space Shuttle) have cryogenic rocket engines. These are rocket engines that very cold liquid propellants. The most common cryogenic engines use Liquid Oxygen (LOX) as an oxidizer and Liquid Hydrogen (LH2) as fuel. Rockets require the fuel and oxidizer to feed into the engines at a very high mass flow rate in order to generate the necessary thrust. The solution is to store oxygen and hydrogen in liquid form, where they are more dense (meaning that they will be fed into the engine at a higher mass flow rate). Because oxygen and hydrogen are gaseous at room temperature, they must be cooled to very low temperatures in order to take on a liquid state. Oxygen must be cooled to -183 degrees C (-297 degrees F) and Hydrogen must be cooled to -253 degrees C (-423 degrees F).
Gases such as water vapor condense when they are heated?
Gases like water vapor typically condense when they are cooled rather than heated. When the temperature of water vapor decreases, its molecules lose energy and come together to form liquid water. Heating water vapor generally causes it to remain in a gaseous state or expand, preventing condensation. Thus, condensation occurs during cooling, not heating.
How are rockets powered?
A rocket is propelled into the air by the exhaust from burning fuel. As the exhaust leaves the back of the rocket, the rocket experiences an equal and opposite reaction, being pushed forward (upward). There does not have to be anything for the gases to push against, so rocket engines (with their own oxygen supply) can work in outer space as well as on Earth.The only way for a rocket to reach an orbit around the Earth is by achieving a very high speed (escape velocity), so that its momentum carries it around the planet instead of falling back as missiles do.
What happened to water vapor before it turns to water?
Water vapor undergoes condensation when it cools down, changing from a gas to a liquid state. Condensation occurs when the air temperature drops to the dew point, causing water vapor to lose energy and form liquid water droplets.
Can you give me 5 statistical facts about rocket fuel?
Here Are The Facts: 1) John McNab the 4th founded rocket fuel 2) He founded it in the early 1900's 3) Henry James tried to steal the idea from him and went to jail 4) 8256.00023 + 856.0232 = 523361.00235 and that's how much fuel you need to get to outer space but not back 5) Rocket fuel was first used January 25th 1968
Which of these is defined as the change in physical state from gas to liquid?
When gases are cooled, they convert to liquids. This is termed as condensation.
What are the examples of a liqiud gas?
A common example is the liquid gas inside a cigarette lighter.
All gases become liquids when cooled to their what point?
All gases become liquids when cooled to their respective boiling points. At this temperature, the vapor pressure of the gas matches the external pressure, causing the gas to condense into a liquid state.
Can all gases form a liquid?
No, not all gases can form a liquid. In order for a gas to form a liquid, it must be cooled and compressed to a temperature and pressure at which the gas molecules come close enough together to form a liquid state. This process is known as condensation.
What are the some example of cryogenic gases?
Examples of cryogenic gases include liquid nitrogen, liquid helium, and liquid oxygen. These gases are cooled to extremely low temperatures to achieve their liquid state for various industrial, medical, and scientific applications.
What gas can turn into a liquid?
water vapor (gas state) can turn into water (liquid state) when cooled.
What physical state of fuel does a liquid fuel rocket use?
It uses fuel which is in the liquid state.
Which state is zero state of matter?
Liquid gases.
What state of matter does water vapor become when it is cooled?
Water vapor becomes liquid water when it is cooled. This process is known as condensation, where the vapor loses heat and transforms from a gaseous state to a liquid state.
Why the liquid state became a solid state?
When it is cooled down below melting point.
When a liquid is cooled it may changes into a new state of matter name that state?
It Is ICE.
When liquid is cooled Its particles become?
At the feezing point the liquid become a solid.Freezing is a physical change.
